Variable support about testcl

[landro]

Glad you like TesTcl, @snorrebrandstadmoen. Have you tried defining this as a global variable?

@landro - I guess the log_level variable could be global, but this was just an example. Typically I want to log ie. session based information like HTTP:uri or HTTP:host in the HTTP_RESPONSE event, and these are unavailable in the "response context" and must therefore be set as an variable in the incoming HTTP_REQUEST event.

F5 has redefined the behavior of the set command - right now TesTcl uses a standard set implementation, where variables go out of scope as you would expect in any programming language. They should have used/defined some kind of exchange/context similar to what you find in SOAP/REST frameworks. Well - whatever - right now you're left with two options:

1. Use global variables (which could work - you might have to define tests in separate files maybe to avoid collisions)
2. Make a code contribution. One could use upvar/uplevel, look at the callstack, and redefine set if called inside when command (otherwise, stuff might stop working elsewhere, since set is a standard command).

I noticed by the way #34 is a similar open issue
